R help - Jan 2005 - Visualizing complex analytic functions using domain coloring

Hi

has anyone coded up domain colouring for visualizing complex analytic 
functions
(such as elliptic functions)?

[
the idea is to depict a complex function f(z) using a filled.contour() 
variant
in which the hue is given by Arg(f(z)), and the saturation by Mod(f(z)).

Hi Robin


here's the C++ code (scale already coded)

!  it was done under C++ builder and I seem to remember that RGB is in fact
coded as BGR (I've done that a year ago and already forgotten all about it,
roll the years!)

the scale was generated from another C++ program (which I do not find for
the moment...sorry! when I find it again I'll send it to you) and seemed to
work to the satisfaction of the clients
